The lever 17 is pivotedforvertical swinging movement as at 19'to; the adjacent side of the body 9,and is adapted when swung upwardly and rearwardly to exert a pull uponthe link 18 for causing rearward swinging movement of the arm 17 andthereby releasing a hook 2() from a keeper 21, that is mounted upon theadjacent sill 8, the hookr being rigid with the crank shaft whichcarries the arm v16.y Furthermore, the lever 17 is of .such a y lengthvasto lproject rearwardly beyond the rear end ofthe body 9 when swung torelease the hook 20, so as to form a levery upon which r.downwardlpressure may. be exerted for causing `thebody 9to be tilted, movment ofthelever 17,v downwardly beyond a predeterfmined point 'being preventedby engagef inentof 'said lever with a'projecting memauv ber ofthe wagonbox.

It is apparent that when the lever.17. is swung f upwardly and forwardly, the hQOk 20fis the device, asshown in Figure y,1, the catch -13,'is 'engaged with the wagonbox endgate y11 for maintaining the latter closedand the .l hook 20"is. engagedwith the keeper 21 for maintaining the body9 horizontal, release of thehook 20 beingprevented by the normal.

feet such tilting ofthe body. As the body tilts, the forward end of thehook 13 is vengaged with the transverse casing 7 and y the hook 13 isthereby swung to disengage in the rear hooked end from the wagon box endgate `11 so that the latter may swing away from the rearend of the wagonbox or body and thereby automatically permit dumping .0f the contentsyof the body 9. In this manner, Vonly operation of the lever 17 isnecessary for releasing the body whereby it may be tiltedl and for.lexertingfa pull upon the body so that-the same is causedy to tilt,

as well 4as effecting the unlocking or unlatching of the, end .gatel11'k whereby the contents .of the body may.v discharge when therlatteris tilted. i c .A

In order to limit the tiltingmovement of the body to `,a properpositiom'the forward end of thebody is connected withthe sills 826between an abutment`29 and the guide 27 so 'as to cushion thepullexerted` upon the chain' 25 when the bod is tilted and to therebyprevent the catc 13 from striking the differential housing 7 1a hardblow such as Vwould causedamage vto these parts. y
